lanterns.

of the burner 3.

The object of the invention mainly is to provide improvements in theflue construction, such improvements being readily adapted, atcomparatively small cost, to the ordinary lanterns as now constructed.

In the drawings: Figure 1 is in the main a vertical section of a signallamp adapted to burn acetylene gas and provided with my improved flue.Fig. 2 is a relatively enlarged detail view partly in section. Fig. 3 isa view of the under side of the parts shown in Fig. 2.

1 represents the main body of the lamp, provided with one or more lenses2-2.

3 is a gas burner.

4.4= are inlet ports in the upper part or dome of the lamp body 1, thesame being provided to supply air to support combustion at the'burner 3.

5 is a tubular outlet flue having a combined guard and deflector hood 6so arranged as to prevent rain or snow from falling downwardly throughthe flue 5, at the same time being so spaced relatively to the upper endof the flue 5 as to permit the products of combustion to readily escape.The flue 5 is supported by an annular drip deflector 7, which in turn issupported by the tubular spacer cone 8 arranged between the inlet ports4: and the flue 5. The drip deflector 7 is provided with a suitablenumber of drip ports 9 or clearance spaces near the outer edge thereofso that any water which may enter the tubular spacer wall 8 from abovewill drip down into the bottom of the lamp body 1 without encounteringthe tip The upper end of the spacer wall 8 is obviously open, so as toprovide a final outlet for the products of combustion, the extreme upperend of the lamp being provided with a suitable hood 1O properly spacedaway from the upper end of the lamp to permit the products of combustionto freely escape, and yet close enough thereto to prevent in a largemeasure the entrance of rain or snow. The shield members 6-10 cooperateto effectively prevent undue down drafts, which, if not checked, wouldtend to impair the efliciency of, or extinguish the flame at the burner3.

By the foregoing construction, it will be seen that the burner is doublyprotected from down drafts and from the admission of snow or rain.

In the preferred construction, the drip deflector 7 slants down,somewhat from the flue 5 so as to more readily direct water toward thedrip ports 9-9. The drip deflector 7 also performs an important functionin controlling the drafts of the lamps in v that it serves as a baffleplate cooperating with the hoods 6-10 in checking the sudden down draftswhich would tend to extinguish the flame, also cooperating therewith inpreventing. sudden vacuum which frequently results in the extinguishmentof the flame.

From the foregoing it will be'seen that the improvements areparticularly adapted to lamps or lanterns in which a comparatively smallflame of high intensity is employed. Where such flames are. employed ithas heretofore been found to be exceedingly difficult to maintain theflame under severe weather conditions, owing to the fact that suchflames, though intense, are more easily extinguished than the lessintense flames of larger dimensions such as produced by the ordinary oilburner.

While I have here shown my invention as particularly applied to alantern of the down draft type, in its broadest sense, it is notnecessarily limited thereto.

What I claim is:

1. In a lantern, a main body, a burner therein, a flue arranged abovethe burner, a drip deflector surrounding and supporting said flue'andprotecting said burner, a cone surrounding said drip deflector, a hoodfor said cone, and a hood for said flue Within said cone.

2. In a lantern, a main body, a burner therein, a flue arranged abovethe burner, a drip deflector surrounding and supporting said fine, andprotecting said burner a cone surrounding the drip deflect-or, a hoodfor said cone, a hood for the flue Within said cone and air inlets inthe main body in 10 a plane between the upper and lower ends of saidcone.
